Vascular Dynamics of Cerebral Gliomas Investigated with Selective Catheter Angiography, Perfusion CT and MRI [PDF]

, 2018
Purpose:: To assess if intratumoral blood circulation parameters from dynamic susceptibility contrast (DSC) MRI and dynamic CT deliver comparable results and to compare tumor-related changes in regional cerebral blood flow (rCBF) and regional cerebral ...

Cerebral Organoids with Integrated Endothelial Networks Emulate the Neurovascular Unit and Mitigate Core Necrosis

Advanced Science, EarlyView.
Fumadó Navarro et al. present an optimized strategy to generate vascular‐like networks that infiltrate within cerebral organoids with promising signs of blood‐brain barrier characteristics, preserved stiffness, uniform morphology, enhanced media diffusion, and reduced necrotic core.

A Quantitative Comparison of Clinically Employed Parameters in the Assessment of Acute Cerebral Ischemia Using Dynamic Susceptibility Contrast Magnetic Resonance Imaging

Frontiers in Physiology, 2019
Purpose: Perfusion magnetic resonance imaging (P-MRI) is part of the mismatch concept employed for therapy decisions in acute ischemic stroke. Using dynamic susceptibility contrast (DSC) MRI the time-to-maximum (Tmax) parameter is quite popular, but its ...

To Tube or Not to Tube? The Role of Intubation during Stroke Thrombectomy. [PDF]

, 2014
In the 10 years since the FDA first cleared the use of endovascular devices for the treatment of acute stroke, definitive evidence that such therapy improves outcomes remains lacking.

Loss of Hepatic Angiotensinogen Attenuates Diastolic Dysfunction in Heart Failure with Preserved Ejection Fraction

Advanced Science, EarlyView.
Increased hepatic angiotensinogen (AGT) abundance leads to cardiac diastolic dysfunction via the AngII‐independent pathway. Liver‐derived AGT is internalized by LRP2 in cardiac endothelial cells, subsequently contributing to myocardial diastolic dysfunction by suppressing microvascular angiogenesis via inhibiting the GATA2/Pim3 pathway.

The cerebral circulation and cerebrovascular disease II: Pathogenesis of cerebrovascular disease

Brain Circulation, 2017
In this paper, we review the cerebral circulation and cerebrovascular disease (CVD) with an overview of the major types of CVD pathogenesis. These, as categorized here, are as follows: occlusive injury intrinsic to blood vessels, occlusive injury ...

Photoplethysmography for Quantitative Assessment of Sympathetic Nerve Activity (SNA) During Cold Stress [PDF]

, 2019
The differences in the degree of sympathetic nerve activity (SNA) over cutaneous blood vessels, although known to be more prominent in the periphery than the core vasculature, has not been thoroughly investigated quantitatively.

Multimodal Imaging Reveals Cerebral Microcirculation Dynamics and Mechanisms in Mouse Central Nervous System After Intranasal Infection With Recombinant Pseudorabies Virus

Advanced Science, EarlyView.
Multi‐modality imaging strategy applied to PRV‐induced central nervous system infection enables dynamic visualization of cerebrovascular dysfunction, including hyperemia, hypoperfusion, and vascular remodeling. These changes are linked to microglial activation and impaired angiogenesis, providing mechanistic insight into PRV neuropathogenesis and ...

Pharmacoeconomical assessment of сerebrolysin in the treatment of the acute disturbances of cerebral circulation

Фармакоэкономика, 2015
: the acute disturbances of cerebral circulation incidence accounts for nearly 70-80% of all such diseases in population, while this annual rate in Russian health care is about 2,19 cases on 1000 individuals. Pharmacoeconomic evaluation of this pathology
